{"id":"CVE-2026-91048","summary":"Apache Karaf: Missing authorization on the jdbc:* shell command scope allows privilege escalation to remote code execution via jdbc:ds-create","details":"The jdbc shell command scope shipped no org.apache.karaf.command.acl.jdbc.cfg. Karaf's command guard (SecuredSessionFactoryImpl) treats a command with no matching ACL rule as allowed, so any authenticated shell session (including one holding only the viewer role) could run every jdbc:* command. jdbc:ds-create stores a fully attacker-controlled JDBC URL into a pax-jdbc-config factory Configuration with no validation. pax-jdbc-config reactively turns that into a live DataSource. Several JDBC drivers run code or SQL at connection time based on URL parameters (e.g. H2 INIT=RUNSCRIPT), so a viewer-level shell user could reach arbitrary code execution, bypassing the admin-role gate that already protects shell:exec. This is a privilege-escalation-to-RCE chain, not merely an \"admin misconfiguration\".\n\n\nThe same applies to jms:* shell commands.","modified":"2026-10-09T02:49:30.730411417Z","published":"2026-09-29T08:34:47.193Z","database_specific":{"cna_assigner":"apache","cwe_ids":["CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/91xxx/CVE-2026-91048.json","unresolved_ranges":[{"extracted_events":[{"fixed":"4.4.12"}],"source":"AFFECTED_FIELD"}]},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/09/28/9"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/91xxx/CVE-2026-91048.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/ph3867mxh2tft75w0o1hpn10f5mbmw32"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-91048"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/apache/karaf","events":[{"introduced":"0"},{"fixed":"189048fff3422afaadcbbb57d95b257cb35248ad"}],"database_specific":{"cpe":"cpe:2.3:a:apache:karaf:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"4.4.12"}],"source":"CPE_RANGE"}}],"versions":["karaf-4.4.8","karaf-4.4.7","karaf-4.4.6","karaf-4.4.5","karaf-4.4.4","karaf-4.4.3","karaf-4.4.2","karaf-4.4.1","karaf-4.4.0","karaf-4.3.3","karaf-4.3.2","karaf-4.3.1","karaf-4.3.0","karaf-4.3.0.RC1","karaf-4.2.3","karaf-4.2.2","karaf-4.2.1","karaf-4.2.0","karaf-4.2.0.M2","karaf-4.2.0.M1","karaf-4.1.1","karaf-4.1.0","karaf-4.0.4","karaf-4.0.3","karaf-4.0.2","karaf-4.0.1","karaf-4.0.0.M2","karaf-4.0.0.M1","karaf-3.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-91048.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
